Yep, you read that right: using tea bags to help heal a broken nail is an industry secret. Cut a small piece out of the tea bag and apply glue to the broken area of the nail. Position the piece of tea bag on the broken area before applying glue one more time. If you don’t like harsh glue, use a top coat as a glue for a temporary solution. You can also paint over the tea bag with nail polish to completely camouflage the break.
